**  Mental Illness Classification SAS Formats ;
**  Two SAS formats are used for classification. The format $psychf groups 3-digit ;
**  long diagnosis codes into the three mental health categories. The format $psychl ;
**  labels the three groups as Major (psychotic), Minor (non-psychotic) and Other ;
**  (other disorders). The labeling does not match the deliverable because the change ;
**  in category labeling occurred late in the analysis.;
